5 Claims. (Cl. 248-74) rI'his `invention relates to spring yclips of the type shown in my ypending application for United States Letters Patent, Ser. No. 502,340, filed September 14, 1943, for supporting in a particular manner a group or bundle of wires or a conduit line, in aircraft or the like.

An object of vmyy invention is to provide a clip of the characterdescribed in the form of a split or open, spring metal band or loop having abutting free ends normally in tensioned contact with kone another and so constructed and arranged that when a wire, or a group o-f wires or a conduit line is forcibly pressed between and against said ends, or when the clip moved in a vcertain manner to press the ends against the wire, or wires, or the conduit line, the ends will readily spread apart so that the Wire, wires 'or conduit line will then readily enter the clip, lafter which the ends will spring back into tensioned contact With one another and due to the shape and arrangement thereof, will effectively prevent accidental or unintentional removal of the wires or conduit, which however, may be removed when intentionally brought into a certain position rela.

tive to said ends and then forcibly pulled there'- between.

Another object of my invention is to provide a clip for the purpose described 'm which a spring metal band is split in such manner that thewires or conduit yheld therein will intersect they split rather than extend parallel thereto, as by means of a diagonal split, whereby the ends Aof the band in being thus formed :and abutting'one another under tension will prevent accidental dislodgement or removal of the wires or `conduit held therein but when the wires or conduit and said diagonal ends are brought in substantial parallelism the insertion and removal of the wires or conduit may be readily effected. Y

Another object is to provide a clip such as described in which the diagonal abutting ends thereof are rounded and outwardly flared to provide a mouth facilitating the insertion and removal of the wires or conduit. Y'

Another Objectis to provide a 4clip such as described in which the vsplit `loop or band thereof is constructed to 'be fastened to a. support intermediate the ends formed 'by the split, so that the wires Aor conduit may be vinserted and removed after the clip is fastened to the support.

A further object vof lmy invention is to provide a split spring clip such as described which readily lends itself to the application of a cushioning strip thereto with a ap portion of the strip lying 'between the split and the wires, to further resist accidental removal of the Wire or conduit therefrom, the said flap portion of the cushion being movable relative to the cushion proper and ends oi the clip to permit of insertion and rei moval of the wires on a conduit. y' With thev foregoing objects in view together with such other objects and advantages as may subsequently appear, the invention is carried into elect as illustrated by way of examplev 'in the accompanying drawing in which: l Fig. 1 is a front elevation of a clip embodying my invention;

Fig. 2 is fa side elevation thereof; Fig. 3 is a horizontal sectional view taken on the line 3 3 of Fig. 1, and showing the clip fasn tened to a support;

Fig. 4 is a perspective view of 'the cli-p as completely installed to support a bundle of Wires;

Fig. '5 is a i'front elevation of the clip showing how a wire and the diagonal ends are brought into substantial parallelism to eiect an easy insertion or removal thereof. Y .A I

Referring more speciiically tothe drawing it will be apparent that one form of :clip embodying my invention generally includes a split spring metal 'band f6 which is adapted to embrace and support a group of wires l on a support 18 to which latter the clip 'is secured by means di a bolt 9 and nut l0. A bolt receiving opening is provided in the band 6 intermediate the ends thereof to receive said bolt which supports the band in such a position that said ends, although having tensioned contact lwith one another may be spread apa-rt to facilitate insertion and removal ofthe wires in a particular manner which will be hereinafter fully described.

In accordance with my invention the split of the band vl is such that the wires heldin the band extend across the split instead of 'parallel thereto, thereby preventing accidental removal of the Wires and making `it necessary to bring the wires and split in substantial parallelism as shown in Fig. '5 to effect la. ready insertion or removal of the wires. l' f 'i Moreover the ends of the band are so formed 'that on pressing the wires against the ysplit when in substantial parallelism therewith; the wi-'res may be readily inserted and removed.

As here shown the split is diagonal and-defines opposed somewhat pointed end portions l,2"2, provid-ed with diagonally extending outward curved or rounded portions l3-l3 which abut one another under tension and are further outwardly extended and flared to form divergent and rounded lips l 4-I 4, also extending diagonalabutpurview 'and concept' hereof.

It will now be seen that when the wires areA brought into substantial parallelism with the split, that is, the abutting portionshllwand lips I4, and pressed against said lips, as shown in l Fig. 5, they may be easily'inserted into the clip.

a spring metal split band for embracing and supporting the wires or conduit; and end portions In similar manner the wires may be removed', it

only being necessary to bring the wires and split in parallelism to effect an easy removal of .the

wires from the clip.

the clip, the-portions I3 of the ends I2 are held lin tensioned contactby the spring action of the band and the wires intersect or extend across the split or in other words, the split extends diagonally and out of parallelism with the wires so that accidental removal or withdrawal of the wires is eectively prevented. In inserting the wires the flared lips I4 serve as a guide and retaining mouth making for a quick and easy` insertion, The lip portions of the-abutting ends produce a groove with side portions which guide the entrant movement of the wire into the band. Likewisea similar mouth is kprovided interiorallyvof the contacting outwardly curved portions I3, to facilitate holding the wiresjin parallelism therewith to effect withdrawal of the wiresl from the clip.

While the clip hereof may, if desired, be eiectively used without acushion strip as a lining for the band 6, I prefer to use as here shown a cushion stripv I5 of elastic yieldable material -such as rubber or the like having rebent flanges I 6 to hold the strip on the band 6. `'I'he-:ends of the cushion terminate shortfof and 1eave`bare'the major portions of.-.the pointed ends I2, except that a flap extension II of the cushion lies on the inner surfaces of the band so as to overlie or extend across the slit and abutting portions I8 ofthe ends I2. In other words the unanged flap extension I'I directly underlies the abutting ends I 2 thereby closing the slit from end to end and preventing, the accidental withdrawal of the wires therethrough. However, the flap I1 is freely movable relative to the cushion I5 proper and the ends I2 whereby it may be pushed aside by thc wires being inserted, and will then spring back in place. It is also pushed aside to bring the wires in parallelism to the slit, when removing the wires from the clip. The extension I 1. makes a 360 degreeV cushion, completely encircling the wires, thereby more eectively cushioning and protecting the Vwires aswell as holding them in place in the clip. y

`While I have shown and described a specific embodiment of my invention I- do not limit my.

on the band defined by said slit so that they abut one another under tension and extend diagonally across the band to eifectively maintain the band closed around a bundle of wires or a conduit mounted in said band.
